To all whom t mag/.concern Be it known that I, JOHN M. PUGKiifi'r, a

citizen ofthe United States, residingA at Elgin, in the county of Bastrop land State of Texas, have invented certain new anduseful Improvements in StorageBatteries, of which the following is a specication.

This invention relates to storage batteries, and the primary object offthe invention is to provide an improved means orconnecting the pillar post to thebattery jar cover, so .as`

to prevent the jarring looseof thepillar post and the consequent `seepingioi the electrolyte or acid 'from the battery.

:Another object of the invention is to provide an improved washer 'for storage ,battei-ies, which is so designed as to support the pillar post and cell connectors orfteriiiinalsE to and forms a. iiuid tight joint therewith -1 and with the yjaifcover7 whereby -the loosenl ing of thepillar post and lossotthebattery fluid is eliminated.

A further object of the` invention is to` provide an improved .washer Awhich can be readily associated with the pillar@ post terminals and which can be constructedso as to conform to the configuration. of any type of battery jar coveror pillar post.

. .A still further object ofr this invention is to provide an improved washer .for storage batteries of the .above .characterwhich r`is durable and eilicientin use, one' that issimple and easy tc manufacture, and onelwhich can be placed upon the market and embodiedl with a storage battery ata minimum cost.

With these and other objects inview, the invention consists in theY novelconstruction,

arrangement and formation.offparts, as 4will i be hereinafter more specifically, described,

. claimed and illustratedin the accompanying drawings, .forming a part-of this specification, in which drawings: ,v Y

'R eferi'ing tozthedrawings in detail, whereiii similar reference characters designate corresponding parts throughout the views, the letter A indicates a storage battery and B the improved washer for use in connection therewithTi `or any preferredconstructionvor make and' ,las shown .includesthe :usual battery `jar 5, the jarcover, the jpillarpost 7` whiclizis connected fin the ordinary manner `te the;`

i The jar Acover 6 isfprovided at itsperimeter with a downwardlyflextendng and outedge of this 4flange is providedfwvitha ysubstantially right angular extension i12 which e.engages the inner suifacefoithe-battery jar. '.The flanged()v and the extension 412fcims 4@means forreeeiving therbattery Asealing com-l pound=13 which may be of theiisualfor or- Adinary variety. Asntheiisual censtruction the cover 6 is 'provided with tliefdepend ingA` sleeve :14 through which thepil'lar post `7 entends. 'Ilheipillarr post 7 has beenfsliown circular in cross .section andgraduallytap ered. towardv itsupper end, .but it i isV to be ,un- .derstood that the post 7 can. bexoflanydesired configuration and tlietwasherB-:is

formed to .contorni to the "crosssectional;

contigui-ation.thereof. u However, 'the best results have .been iiound with the use of the tapered pillar posts. The` lowerv end. of fthe rsleeve ,14,21 is provided with .an 1 inwardly eX tendingright angular flange 15.which.`is-

,adapted toengage the, outer` vfaceof thebase .of thelpillar post 7:. The .sleeve 111 as shown alsoprojects slightly from Athe top foi .the cover plated` The battery terminal for lcell connector 9 is also fof the usual,constructionand as shown includes the annular .body 16, whichmay-be welded ory secured in anyraother preferred Y niaiinerto the `upper endfoiE therpillar post 7,

and the Aoffset portion 16 to avhi'chthe-leadf-l to or from the battery may be connected.

If-s0 desired,` artaperedsleeve 417may beassociated wit-h the; annular right .angular extension 15 soas toaform awell 18jlor the .sealing lcompound 19 which Vmay be fof the.

yusual type.. If so desired {thetaperedvsleeve 17.1naybe formedintegral withthe right angular extension 15.... The improved Ywasher B which forms thegsubject inatteriof the presrial, 4preferably softV metal, such as lead and includes an annular body 2O which is formed substantially flat and is adapted to engage the UPPGY edge 0f ih@ extended portion of rthe sleeve 14,

wardly yinclined;.flange V10,` and .thevlower-f .ent .invention may lbeformedrof any-mate-lV The inner edge of the annular body is adapted to tightly fit the outer surface of the pillar post 7 so as to form a fluid tight joint therewith. The upper surface of the body 20 has formed integral therewith the upstanding flange 21, which is spaced a slight distance from the inner edge of the body 20. This flange 21 is adapted to engage the lower surface of the battery terminal or cell connector l9 so as to form a support for the same and to form a tight joint therewith. The lower surface of the body 2O is provided with `a depending'flange 22 which 4s'arranged in spaced relation to the outer edge of the body 20 and this fiange is adapted to tightly engage the sleeve 14,y

so as to form la fluid tight joint therewith. In use oftheimproved washer, the pillar 'post 7is inserted in the sleeve 14 in the` usual manner and the battery'sealing compound-1s poured around the same, atter which the washer Bis inserted over the pili lar post and pressed tightly down into firm engagement with thek sleeve 14. Owing to the shape of the sleeve 14 andthe iange 22, the inner surface of the annular body 20 will be forced into tight enga-gement with the pillar post 7. It will be further noted that the compound 19 will be forced downwardly and inwardly towards the sleeve 17 and post 7 and placed under compression so asto provide a fluid tight sea-l and prevent the leakage of electrolyte or other acid from the jar. The battery terminals or cell connector 9 is then placed in position on the upper edge of the pillar post 7 in engagement with the upstanding ange 21 and the same is welded or otherwise secured into Vposition as is common in the ordinary conwith a jar cover having a terminal post opening thereln, a sleeve arranged 1nV said i opening and extending above and below'the same, a right angular extensionf'formed-on the lower edge of the sleeve, a collar arranged on said extension in 'spaced relation to the sleeve, a terminalpost extended through said 'opening and engaging said collar, a sealing compound arranged around said post and said sleeve and collar, and a terminal lug fitted on the upper end of said post, lof a washer formed of soft metal including an annular body having its inner edge in frictional Huid tight engagement with the post, and its lower surface in engagement with the upper edge of the sleeve, a depending annular flange formed on the lower surface of the body in frictional engagement with the inner wall of the sleeve, and an upwardly extending'annular iange formed on the upper surface of the body arranged in spaced relation to the post forengagement with the terminal lug.

2. In a storage battery construction the combination of a jar'cover having a pocket, a terminal post extending upwardly through the pocket, a filler of sealing compound in the pocket about said post, and a terminal hub fitting about the post and forced downwardlyinto closing engagement with the upper end of the'pocket and engaging the sealing compound to place the compound under pressure and force the same into close engagement withv the post and walls of the pocket.

3. In a storage battery construction, a jar cover having a pocket, a terminal post extending upwardly through the pocket, sealing compound in the pocket about the post,

and means for closing the upper end of the pocket about the post and applying pres- Va disk fitting about the post and forced downwardly into engagement with the upper en'd of the pocket, an annular rib vextending from the disk into. the pocket in contacting engagement with 'the walls of the kpocket and'in spaced relation to the post and adapted to move the compound towards the post when the disk is forced downwardly to place the compound under compression, and means vfor retaining the disk in a depressed pressure exerting position.

5. In a storage ybatteryy construction, a jar cover having a pocket, a terminal post extending upwardly through the pocket,

and sealing compound in the pocket about the post and compressed to provide tight engagement withvthe post and walls of the pocket and prevent leakage.
